Wow, normally I'm not big on perforated leather but this works really, really well. The combination of the black dial, gold accents, and perforated brown leather makes me think of the interior of a vintage racecar.

Nice. I'm wearing my Tuna on a 24mm oxblood leather with Panerai-style buckle. I mention the buckle because an important aspect of the strap's good looks is that the buckle size visually balances the large watch case, and matches the beefiness of the strap itself.
